The near wake of a slender body with a turbulent boundary layer (TBL) is characterized by having a small recirculation region. The recirculation region is surrounded by a ring of small scale turbulence that emerges from the boundary layer and does not show strong vortex shedding [1]}, [2]}, [3]}, [4]}. As a result, the wake is thin and develops slowly compared to the wake of bluff bodies. These particular features of the slender body high-\(\)  near wake lead to interesting effects further downstream: (i) despite having a smaller drag coefficient than bluff bodies, the defect velocity (\(U_d=U_\infty -U\) ) of the slender body wake can be larger than that of a bluff body for a long downstream distance, (ii) the turbulent kinetic energy of the wake shows an off-center radial peak at the location where the turbulent boundary layer separates – instead of a Gaussian profile with a central peak, and (iii) helical instabilities come into play only in the intermediate and far field of the wake. These particularities affect the scaling laws of the wake. In a domain spanning \(80D\)  the defect velocity, the kinetic energy, and the dissipation do not follow the classic high-\(\)  scaling and they decay differently than bluff body wakes [4]} exhibiting a non-equilibrium scaling of dissipation [6]}, [7]}.
